18V 6.0Ah Battery Replacement for Milwaukee 18v 6000mAh Lithium Battery Compatible with Milwaukee 18v Battery 48-11-1850 48-11-1852 48-11-1850R 48-11-1840 48-11-1828 48-11-1820 (2 Pack)

These actually hold a charge better than I thought they would!

Works just like name brand for much less

I used these while building my house and my buddies are out needing to use mine and their various tools. Don’t have power on site yet so power is in numbers, of batteries that is. I wound up using these with an SDS hammer to drive ground rods 5/8” down trough bed rock. We wiped out a 12ah high output Milwaukee and the. Turned to these. I don’t think these lasted as long as a factory battery but they provided the power needed. Even though the didn’t last quite as long, they didn’t give up in a short time either, they still ran that SDS for solid periods of time I’d have to guess pushing 25min each or longer.

Ì picked these up to have on hand as spares for my Milwaukee M18 devices. I had high hopes that a new kid on the block would not overinflate the capacity. The first thing I did was charge them on the Milwaukee charger to full. I then load tested both batteries at 3A to a low cutoff voltage of 14.0VDC. When the tests were over, they came in at 3.87AH and 3.91AH - that's well below the rated 6AH capacity (35% less)!Although the listing states overcharge, overdischarge, overcurrent protection, short circuit protection, etc., I'm a bit reluctant to test these out in a high current device since the capacity can't be trusted. I will only charge these when I'm near the charger. At $90, I'd just buy a real Milwaukee battery with rated capacity and not worry about safety.Batteries made in China.

I purchased the 18V 6.0AH Capacity Battery as a replacement for my Milwaukee tools, and overall, I'm quite satisfied with its performance. These batteries are compatible with several Milwaukee models, which is a major plus. They fit perfectly in my tools, and I appreciate that they come in a convenient 2-pack.The 6.0AH capacity provides a good amount of power, allowing me to work for extended periods without constantly swapping out batteries. It's a noticeable improvement over the 3.0Ah and 5.0Ah batteries I've used in the past.However, the reason I'm giving this product 4 stars instead of 5 is because these batteries are not OEM Milwaukee batteries. It's important to note that they are third-party replacements. While they work well and haven't given me any issues so far, I can't help but wonder about their long-term durability and how they will hold up over time compared to the original Milwaukee batteries.That being said, if you're looking for a cost-effective alternative to Milwaukee's own batteries and don't mind the non-OEM status, these 18V 6.0AH batteries are worth considering. They offer good performance, decent capacity, and are compatible with a range of Milwaukee tools. Just be aware that they are not the genuine Milwaukee product.

These batteries are great. They work with my Milwaukee drill 👍😁

These batteries are defintely cheaper build quality than the OEM batteries. The plastic shell does not seem very tough at all, and I wouldn't expect them to survive most drops. I noticed that the batteries don't fit perfectly onto my Milwaukee tools. You kind of have to force them on and they don't always seat correctly.I tried one of the batteries on a small 100CFM leaf blower and it ran the blower just fine. I'd estimate that I got about 10-12 minutes of use out of it on a half charge, so not terrible.Realistically, Its performance is probably closer to a 3Ah battery when compared to the OEM batteries, but it is an OK performer for lighter load tasks.I tried its 9Ah big brother on my Milwaukee edger, which failed to operate the edger once it dropped below half a charge. I suspect these smaller 6Ah batteries will perform similarly poorly on higher load tasks, and I probably wouldn't recommend any batteries from this brand for tools that require a greater power draw.You'll have to decide for yourself if these batteries are worth the price, but they could have some merit for lighter use cases if the price is low enough.

A lot of these aftermarket batteries just have the batteries straight wired to the output prongs, but these actually have a bms (battery management system) amd that makes a huge difference in safety and longevity of the cells. I can actually recommend these batteries as long as they stay with using a bms inside.
